Michael Jumper commented on GUACAMOLE-739: ------------------------------------------ This is not a bug; the 256K limit on clipboard size is intentional. See: * https://github.com/apache/guacamole-server/blob/5e2ddb890a90e840a419f4878381b0c511cc6f25/src/protocols/rdp/client.h#L67-L70 * https://github.com/apache/guacamole-server/blob/5e2ddb890a90e840a419f4878381b0c511cc6f25/src/protocols/ssh/client.h#L25-L28 * https://github.com/apache/guacamole-server/blob/5e2ddb890a90e840a419f4878381b0c511cc6f25/src/protocols/telnet/client.h#L32-L35 * https://github.com/apache/guacamole-server/blob/5e2ddb890a90e840a419f4878381b0c511cc6f25/src/protocols/vnc/client.h#L52-L55 {quote} ... the remote session appears to have a character limit as apposed to the previous version. {quote} The 256K limit has actually been in place for roughly five years. > Character limit on RDP Clipboard > -------------------------------- > > Key: GUACAMOLE-739 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-739 > Project: Guacamole > Issue Type: Bug > Components: guacamole, guacamole-client > Affects Versions: 1.0.0 > Environment: Guacamole Host: Ubuntu Server 18.04 > Hardware: 2 Cores & 4GB RAM > Guac Client: 1.0.0 Release > Guac Server: 1.0.0 Release > Tested on Chrome 72.0.3626.109 64-bit, Windows 10 Professional > Reporter: Gary Miller > Priority: Minor > > When attempting to use the new clipboard API, copying and pasting from the > clipboard in the remote session appears to have a character limit as apposed > to the previous version. To test this I created a text document and > continuously filled the file until I got to the point in which the clip board > functionality ceased. > > Based on my testing, the clipboard would not copy text after the selection > content exceeds around 262,000 characters, I removed /r & /n characters just > to eliminate the possibility of the bug being related to new lines > specifically and I can confirm that this issue occurs even if a single line > exceeds the aforementioned value. > > h4. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
